PG - 671-8 AB - Cytogenetic and fluorescence in situ hybridization (FISH) analysis of 10 patients with various hematopoietic malignancies revealed the presence of dicentric chromosomes or pericentric chromosome rearrangements. Dicentrics were only ascertained by FISH studies in six patients. Two types of pericentric chromosome rearrangements have been observed: 'classical' dicentrics with two clearly separated centromeric regions, and more unusual rearrangements with a breakpoint within the centromeric or heterochromatic area, but outside the alphoid domain. FISH analysis of partial chromosome 1 q duplications present in three Burkitt lymphoma cell lines confirmed the partial involvement of the non-alphoid centromeric domain in the duplicated chromosome segment. The incidence of centromeric and pericentromeric rearrangements in hematopoietic malignancies may be higher than hitherto admitted. The chromosomal localization of these rearrangements suggests several mechanisms possibly involved in the malignant process and deserves more systematic study.
